v6 Claims.

This invention relates to hair'driers for use in drying a persons .hairin beauty parlours and thelike.

Themain object of the invention is to .provide a .compact assembly ofthischaracter which will provide for the efficient drying of. hair and.which will avoid the disadvantage .ofhaving the hot air currentblown.down.ov.er the head andface of the personbeing treated.

Afurther object of the invention is to arrange for the removal of thewarm air from the head area of the person being treated .by simple andconvenient means co-operating with .the air impelling means of thedrier.

A still further object of the invention is to provide an apparatus of.this character which can be manufactured 'at a .comparatively lowfigure.

With these and other objects in view the invention consists essentiallyof a casing enclosing a heating element and air impeller, the casingcarrying a head piece or helmet, designed to fit over the head of theperson being treated and communicating with the interior of the casingso that air may be impelled from the easing into the head piece and intocontact with the hair. Along with this construction is provided an airwithdrawing channel which is built on the casing and communicates withthe top of thehead piece, the .channel communicating withthe. fan end ofthe casing, and thereby under. the influence of the airimpeller so thatair impelled into the head piece, after contact with the hair, iswithdrawn under .the force .ofthe one impeller, asmore fully described.inthefollowing specification and illustrated in the accompanyingdrawing which forms part of the same.

In the drawing:

Figure 1 represents a side elevation of the hair drier.

Figure 2 is a rear end View of Fig. l, and

Figure 3 is a view similar to Fig. 1 showing the casing and relatedparts in section.

Referring-more particularly to the drawing, A indicates the hair dryingapparatus as a whole which comprises a casing l0 mounted upon a suitablebase II. The casing Ii! forms a general air passageway l2 and houses thefan l3 and resistance heating elements M which are positioned in advanceof the fan. The fan motor and resistance elements are connected insuitable electrical circuit so that, when closed, the fan will operateand the resistance elements will be heated whereby the current of airimpelled by the fan within the passageway l2 will pass by the.resistance elements to cause the air to be heated.

The aircurrent isimpelled toward the forward end of thecasing which hasmounted thereon in any. suitable manner a head piece 55. This head pieceis perforated or orificed as at it and its exterior .wall. ll throughoutis accessible to the air passing from passageway l2. In this connectionit will be noted that the outer casing member iii of the head piece isspaced from the outer surface H by the air channel 59 so that the .air;from the passageway l2 may be circulated vcompletelyaround the sides ofthe head piece. In this Way,,therefore, when persons having their hairdried have the head piece mounted on theirheads and over their hair, hotair is blown throughthe hair to dry it.

In many types of construction, however, the hot -air. blown. through thehair has only one outlet, namely, down between the head piece andthe'head and thus it blows over the face of the person being treated.This results in a very disagreeable condition. In some cases provisionhas been made to avoid this dimculty but this has necessitated a morecomplicated form of apparatus.

In the present case, means have been provided for withdrawing this airfrom the headpiece after it has passed through the hair so that it willnot be impelled down over the face of the person being treated. Thismeans is embodied in a simple form of apparatus requiring very little.added construction and no additional apparatus for .air withdrawal.

Upon referring to- Figure 3 particularly, it will be seen that the topof the head piece is formed with a passageway or duct 2i? whichcommunicates with an air withdrawal channel 2 8, formed along the top ofthe casing and terminates at its rearward end, opening to theatmosphere. On the rearward end of the casing til is provided a damperarrangement including a plurality of substantially segmental openings 22which may be screened as at 23 and controlled by a suitable damper orvalve member 24 operated from the operating knob 25. It will be notedthat the rear end of the casing which, as shown in Figure 3, is in theform of a closure cap 26 has three of the substantially segmentalopenings 22 spaced equi-distant while a fourth opening is closed by a.conduit member 21 which is provided with an extension or nozzle-likepiece 28, designed to fit into the rearward opening of the channel 2| sothat communication is established between this channel and the rearwardend of passageway l2 behind the fan [3, consequently suction isestablished in passageway 2| and therefore hot air which is blown intothe head piece I5 is thereafter removed through the passageway 2| andwill not be propelled over the face of the person being treated.

In this way the apparatus provides for the removal of air from the headpiece without the necessity of employing any additional suctionapparatus while the construction, it will be noted, requires very littleby way of addition to the conventional apparatus to effect this desiredend. The arrangement is such that all the parts are compactly arrangedso that the device may be built readily and produced at relatively lowcost. Y

It will be apparent that any number of openings 22 may be employed inthe end plate 26 or the end of the casing, while the openings areprovided with the screen 23 of suitable mesh to avoid dust particles andthe like. In the passageway 20, Screening 29 may be positioned,

while within the passageway I2 a baffle member or air deflector 30 maybe employed to direct the air currents more efficiently to all parts ofthe head piece.

Various modifications may be made in the invention without departingfrom the spirit thereof or the scope of the claims, and, therefore, theexact forms shown are to be taken as illustrative only and not in alimiting sense, and I desire that only such limitations shall be placedthereon as are imposed by the prior art or are specifically set forth inthe appended claims.

We claim:--

1. A hair drying device comprising a casing enclosing an air passageway,an air impeller and heating element mounted within said passageway, ahead piece mounted on the casing orificed over a major portion of itssurface to communicate with said passageway, an air channel above saidpassageway extending between said head. piece and passageway forremoving hot air introduced to the head piece-from the passageway, saidair channel communicating with the suction side of the air impeller, anddamper means in the end of the casing communicating with the atmosphereto regulate the supply of fresh air to said passageway.

2. A device as claimed in claim 1 in which the damper means include aplurality of openings in the rearward end of the casing, and a valvemember for regulating the size of said openings.
